yes, I've actually just started experimenting not using darks myself. I just use a DSLR that isn't cooled, as long as you dither between subs and get enough data and enough subs (I am aiming for a minimum 16) it seems to take care of noise.
Applying flats have been the most useful addition to my pics, they make the biggest difference to an astrophoto in my view. if you haven't much data though applying darks is a good option.
